This inventio-n relates to machines designed for the extermination of insects, especially boll weevils, worms, fleas and similar insects of hindrance to the production of cotton and produces, its principal object residingin the provision of animproved insecticide dispensing hopper capable of. establishing. equal distribution ofpoison, usually in the form of powder, generally calcium "arsenic or sulphur.

`The invention further aims among its objects to .provide a means for controlling an air draft through the hopper7 .hence to govern the quantity ofpoison dispensed therefrom in this manner.

Broadly, the invention comprehends a machine having such operative facilities as to enable it to evenly and definitely distribute insecticide through a series of distributing conduits accordingly-with the air force supplied by a blower, and consequently prevent waste of the material used according to other methods.

With these foremostobjects in view, the y'invention has particular reference to certain novel features of construction, referred to in detail in the course of the following description and illustrated in Vthe accompanying drawings, wherein:

Figure 1 represents a front end elevation of a machine constructed according to the present invention.

Figure 2 is a side elevational view thereof.

Figure 3 is a detail view of the hopper.

and blower attached, and

Figure 4 is an axial cross sectional view of the hopper.

Continuing now more in detail with the drawings, in Figures l and 2 is illustrated' a preferred embodiment of the invention composed primarily of a platform 1, supported upon wheels 2. A. blower 3, the construction of which is commonly known, is supported upon the platform, near the front andV immediately behind the blower is mounted a hopper 4 of any suitable capacity. A conduit 5, preferably rigid is 'supplied as a conveyance of air from the blower 3 to the hopper 4, whence the air, together with the agitated poison contained within the hopper is carried under pressure in equall distributed quantities into the flexd ible d stiibuting conduits 6, thence through distributing nez'zles 7 directly ont@ the COTTON-DUSTING MACHINE. 1

vegetation over which the machineis being drawn,yeither by horses, engine or other means of traction. The conduits 5 and 6, as well as other details of construction-being Well known in the art,`the description will not dwell thereon at length.

Referring now particularly to Figures Q3 and 4, 'the invention is illustrated as comprising primarily, a square or flat 4rod 8 vertically mounted in rotatable krelationshi within the hopper 4, and passingfthroug its bottom 9 the rod has affixed thereto' crown wheel 10, with kdownwardly directed teeth, which areengaged by a gear 11 aiiixed toy arlateral shaft 12 protrudingthrough a' bearing 13 at the sideV of the hopper, and

upon which a sprocket wheel 14is mounted.

this sprocket, and another l16, lwhich in yturn 1smountedv upon a shaft,V 17, drivenlthough a chain 18 from the hub ofl the wheel' 2. See Figurev 1. V f` Returning to the hopper 4, thev centrally mounted rod8 has slidably supported. thereonl acylindrical member 19, near the bottom .of which is attachedr agitating wings 20,

arranged diametrically opposite. As indicated above, and suggested by the broken Alines onfthel drawing, the member 19 is capableof vertical sliding movement onthe rod 8 asthe contents vof the 'hopperare depleted andblown :according to the `direction ofthe arrows through the ports v2`1"communicating with the conduits 6. The mema shaft 23 in which is mounted the sprocket 18, mentioned previously, which likewise imparts driving power to shaft 17 through gear 24 also carried by shaft 23.

The constant draft of air created by the blower 3 enters the hopper 4 at its top through conduit 5, and aided bythe fast revolifing agitator 19, forces the commodity in eqjialized volume out through ports'k '1, flex i 1e tendrias 6 and distribute-f es' 7i .Aas apparent inFigure 3, a chain 15 surrounds To alter the current of air supplied by the blower 3, a sliding `plate is pivotally mounted adjacent the intake port 26 in the blower and arranged to be moved relative to the Vport to lessenor Aincrease the Vintake thereof, consequently controlling the air finally entering the hopper 4. Y. i

It is obvious that since the member 19 is supported lightly upon the commodity, its

penetration isslight andconsequently agitates only that immediately on the surface What is claimed is: v
